Glossary:Gas transmission system
A pipeline system for transport of gas, which mainly contains high- pressure pipelines and compressor stations. (Note that this does not include upstream gathering pipeline networks nor pipelines primarily used in the context of local distribution of gas, with a view to its delivery to customers).
(Note - Transmission lines transport natural gas across long distances and occasionally across interstate boundaries. They are connected to the distribution grid via city gate stations and/or pressure regulating stations.
High-pressure gas transport over long distance including pipelines, compressor stations, metering and regulating stations and a variety of above-ground facilities to support the overall system. Underground gas storage and LNG terminals are excluded. Operating pressure is normally equal or greater than 16 bar.)[1]
